1. -1
Start at -1 on a number line. Move 0 right. You land on -1.
2. 6
Start at 3 on a number line. Move 3 right. You land on 6.
3. 3
Start at 1 on a number line. Move 2 right. You land on 3.
4. -10
Start at -1 on a number line. Move 9 left. You land on -10.
5. 6
Multiply the sizes: 3 × 2 = 6. Same signs give positive, different signs give negative. Answer: 6
6. -17
Multiply the sizes: 1 × 17 = 17. Same signs give positive, different signs give negative. Answer: -17
7. 216
Multiply the sizes: 12 × 18 = 216. Same signs give positive, different signs give negative. Answer: 216
8. -38
Subtracting 19 is the same as adding -19. -19 + (-19) = -38
9. 288
Multiply the sizes: 12 × 24 = 288. Same signs give positive, different signs give negative. Answer: 288
10. 783
Multiply the sizes: 27 × 29 = 783. Same signs give positive, different signs give negative. Answer: 783
11. 91
Multiply the sizes: 13 × 7 = 91. Same signs give positive, different signs give negative. Answer: 91
12. -261
Multiply the sizes: 29 × 9 = 261. Same signs give positive, different signs give negative. Answer: -261
